Okay, so this is a definite newbie XSL question that I am hoping that 
someone can help with. 

Generic Question:
	If I have a comments section that has 1 or more comment complex type 
elements, is it possible to determine if there are at least one comment 
elements that do not have blank children elements?


Detailed version:
 I receive a sample XML file similar to the following:

<document>
	...
	<comments>
		<comment>
			<author></author>
			<reference></reference>
			<date></date>
			<data></data>
		</comment>
		...
	</comments>
	...
</document>

The case is that the file will always contain a comment although it may be 
blank as demonstrated above.  I can use <xsl:for-each select="comment"> to 
loop through each comment but I do not want anything to be written out if the 
comment is blank.  

How can I check to see if the fields under <comment> are blank?

SCENARIO 1:
--------------------------------------------------------------
		<comment>
			<title></title>
			<author></author>
			<reference></reference>
			<date></date>
			<data></data>
		</comment>

Expected Result:  Actual count = 0.  print nothing

SCENARIO 2:
--------------------------------------------------------------
		<comment>
			<title></title>	
			<author>John Doe</author>
			<reference></reference>
			<date>08/01/2005</date>
			<data></data>
		</comment>
		<comment>
			<title>Test</title>
			<author>John Doe</author>
			<reference></reference>
			<date>08/01/2005</date>
			<data>This is a test</data>
		</comment>

Expected Result: Actual count = 1.  Print just the John Doe record

How can I strip out or ignore the blank records?  

The problem is that this goes into a black box that we do not have control 
over so if there was no comment received then we get.  We can fix the front 
end so that a record has to have a title/reference/data in order to be saved 
and that will fix SCENARIO 2, but I am still left trying to fix that blank 
record from SCENARIO 1.

I currently just print out everything using the following (please not this 
is a stripped down version so if there are typos it is from crafting it for 
this message not for the actual implementation):

		<xsl:apply-templates select="Comments" \>

		-		and		-

		<xsl:template match="Comments">
		<div>
			<p>
				<table width="100%" border="0" cellpadding="0" cellspacing="0">
					<TR>
						<TDwidth="50%">
							<STRONG>Comments</STRONG>
						</TD>
						<TD width="50%">  </TD>
					</TR>
				<xsl:for-each select="Comment">
					<tr>
						<td> 
							Title: <xsl:value-of select="title"/>
						</td>
						<td>
							Link: <a>
							<xsl:attribute name="href"><xsl:value-of 
select="reference"/></xsl:attribute>
								<xsl:value-of select="reference"/>	</a>
							 	</td>
					</tr>
					<tr>
						<td>
							Comment By: <xsl:value-of select="author"/>	  </td>
						<td>
							Date: <xsl:value-of select="date"/>  	</td>
					</tr>
					<tr>
						<td colspan="2">
						Comment:<br />
							<xsl:value-of select="data"/>
						</td>
						
					</tr>
				</xsl:for-each>

				</table>
			</p>		
		</div>		

	</xsl:template>

Thank you for you help.
